Recently I had noticed that when my penis is flaccid it looks like it is being constricted in the middle of the shaft. It is a very thin constriction, and when I start to get erect the upper and lower part of my shaft get bigger while the constriction is still there and when I get a full erection it disappears. I noticed this a couple of weeks ago after my penis start getting sore from being gripped and rubbed a little too hard and being dry humped. I waited a week for it to heal before doing anything again, and it looked like it started to get better, but then (stupid me) I tried starting a PE routine and started out by trying to find out my LOT and now its back. Oh, and when I first started letting my penis heal from being sore there was discomfort and pain that eventually went away. Much appreciated if someone can help me out!

I haven't heard of this before. It does sound a bit concerning. Well first off I would suggest that you'd best see a doctor about it actually.

Is there any pain?

So it seems to come from stretching would you say? How intense do you do your stretches? Too hard can cause it to turtle and can be less effective than a medium stretch.

Unfortunately you probably need to wait much longer than a week for it to heal, during which time you could apply heat. When it has healed I would then suggest slow jelqing with a light grip and then edging, and steer clear of stretches for a good while. Injuries can take a long time to heal fully.

There is very little pain here and there, but not at all frequent as it used to be.

Also, Im not sure if it comes directly from stretching but it did seem to come back after I did stretch. My stretches I don't think were at all intense, for I was being extremelycareful when doing it. Although Im not sure if it turtled? Sorry, Im a newbie. Is that what it sounds like or some other effect?

I just started applying heat to it today. I think I'll try letting it heal for at least a month. Although that does seem like a long time, however, I'm sure its better safe than sorry when it comes to this kind of stuff!

I'm trying to think of what could cause such a thing. I hope that it's at least a good sign that it goes away with a full erection. I'm not very good at playing doctor, because, well, I'm not a doctor. But the more I think of it, the more concerned I am. I'm probably picturing it in my head far worse than it is.

The Corpora Cavernosa. Where all the blood fills in, is it possible that the chambers have kinda shrunk in response to the PEing? This would explain why the center of his penis is thinner, but at the same time goes full when erect - they aren't damaged just fallen in on themselves?

Hmm those chambers are filled with a myriad of veins and connective tissue and muscle. More delicate than we think. Although, again I'm only pretend doctors with a potentially serious issue, but... I would think that an injury in that tissue would have the possibility of a full recovery in time. I hope so. Still think a doc should check it out.

It does look like it is constricting in the Corpora Cavernosa. Let me clarify, the constriction is more of just a line going around the middle of the shaft. If it has just fallen in on itself, will it most likely repair itself?

Also, its not from any PE exercises because this started happening before I tried any.
